TO ALL WHOM IT MAY CONCERN:

Be it known that I, DWIGHT J. OSBORN, of Windsor Locks, Hartford county, State of Connecticut, have invented a new and improved Sash-Supporter and Fastener; and I do hereby declare that the following is a full and exact description" thereof, reference being had to the accompanying drawings, and to' letters of referonce marked thereon.

This invention consists in a double'sash-supporter, arranged at the junction of the two sashes ot a window in such a manner as to support both at certain points, or either one separately, as desired; also so arranged that it may be used to fasten beth snshes, theV one up and the other down, so that the window cannot he opened with# out moving the latch which operates the supporters. In the drawings- Figure l is a section through a window frame, showing both sashes.

Figure 2 is a partial inside View ofthe frame, showing the situation of thesupporter.

Figure 3 shows the supporter with the parts in one position; and

Figure 4, the same with the parts in another position.

In construction this supporter consists simply of arplate, A, arranged to he fastened to the sash frame, on which are arranged the three-armed piece B, having pivoted to each end, II I-I, the pieces e e', which act as supporters and fasteners, thc whole being operated by a knob or handle attached at I).

Its operation is as follows: When the parts are in the position shown in hg. 3, both ofthe projecting pieces e c arc removed out from the notches formed in the sashes 4to receive them, and the latter are free to morewhen they are brought to the position shown in iig. 4, which is done by simply moving the handle attached at l) in a downward direction. One of these supporters e has entered the sash fastening or supporting it now by using the pivot Has a fulerum; and further continuing the downward movement of the handle D, the picco e may also he brought into the sash, or by allowing this handle to remain in its horizontal position, but giving it a lateral motion, the projection c may be withdrawn freni its sash and the projection c forc-edinto the other, so that by moving this handle in an upward, downward, or lateral direction, these supporters may be placed in positions so that they either leave the sashes frcc to move or support or fasten one or both of them.

In this simple, manner I form a fastener and supporter which `operates on both sashcs, and saves tno necessity of attaching a separate supporter to each.

The piece G is used to hold the handle D in place, so that it cannot be moved when the sashes are fastened.

And new, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement, upon the plate'A, of the part D, operated by the handle D, in combination with the pieces c c', having projections upon them for the purpose of entering and supporting the sasaes, substantially as set forth. V g

2. In combination with thc-supporter constructed as above, the piece G, for fastening the handle D, substantially as set forth.
